Gardz® is another high-performance interior-use product from Zinsser which every maintenance and project manager should have to hand. Like so many of Zinsser’s paints and coatings range, Gardz® is a specialist problem-solving product – a water-based sealer for porous surfaces. Formulated to deeply penetrate surfaces and substrates, Gardz® will dry to a hard and moisture resistant film, sealing and binding down porous, chalky and crumbling surfaces.

Recommended by Zinsser for use on damaged walls, failing paints and textured finishes, damaged or new drywall, spackling and joint compound skim coats, calcimine, uncoated wallpaper (see also Zinsser Wallpaper Cover-Up), lining paper, filler and wallcovering adhesive residue. Gardz® sealer can repair torn paper and remove bubbles from drywall. It seals old wallpaper adhesive and with food alkali resistant properties, Zinsser Gardz® can therefore be applied to high pH surfaces. To clean the application equipment, this water-based product simply requires soap and water.

Touch dry in 30 mins, or hard dry to a water-resistant finish in 3 hours, it is also recoatable in just 3 hours. As with other Zinsser products stocked at Rawlins Paints, this allows for maintenance and redecoration after repair work to be quick and easy, minimising downtime, VOCs and cost.

Gardz® dries to a clear finish and is not recommended to be, nor is it sold as a tintable product.

We have a problem internal wall. It was originally builtas an external wall late 18th/early 19th century of mixed north pennine stone with lime mortar. For about 45 years it has been used an an internal wall, covered with gypsum plaster and paint. In patches something causes any paint applied to bubble after about 6 months. Would this product help to solve the problem ?

Nick from Barnard Castle (England) - 02/01/17


Based on your description we would recommend using Zinsser AllCoat (Solvent-Based) and leave this as the finish. Zinsser AllCoat (Solvent-Based) is breathable and will let traces of moisture through the paint film without causing the coating to bubble up, it also has good resistance to high pH.

Zinsser Gardz would seal the substrate and could cause a build up of moisture behind the coating resulting in blisters forming over time.

I have grease stains on my emulsion wall, can I use this as a blocker before reprinting?

Geraldine from Wolves (Uk) - 17/06/16

Zinsser Gardz is not a stain blocker, you would need to clean the area well to remove as much grease as possible then apply Zinsser B-I-N

Best recommendations are to spot prime the stain, allow to dry for a minimum of 45mins before applying a full coat to the whole area or to a natural break, allow to dry for another 45mins and then apply your chosen decorative finish (paint or wallpaper).

Can I paint over this with gloss paint or silk paint?

muriel dyga from fraserburgh (scotland) - 11/02/16

Nearly all conventional decorative finishes can be used over Zinsser Gardz including emulsions, wallpaper, solvent based primer, undercoat and gloss.

Is Zinsser Gardz effective in stabilising distemper coated ceilings?

robert jones from Chelmsford (Essex) - 16/06/15

No, we don't recommend water based products to be used over distemper. We would recommend either Zinsser Grade 1 or Zinsser AllCoat (Solvent-Based).
